Foundry sand mixer - 5060-HP
The heart of each sand coating plant is the mixer. It mixes all the raw materials and executes all the process steps determining the quality of the coated sand.The construction and material of all parts getting into contact with sand are designed to have a long life. The mixer wall in the direct mixing area consists an easy to replace steel lining. In addition, the mixing plows are provided with an armor of wear-resistant material. A powerful motor puts the crosshead with the plows and mulling wheels into motion. Within a very short period of time, the resin is mixed uniformly with the sand. The heat transferred from the sand to the resin makes the resin melt to form a uniform resin coat around each sand grain. After adding ol hexamethylene-tetramine and cooling water, cooling air is blown from the lower side of the mixer through the sand, thus cooling the sand and hardening the resin coats onto the sand grains.
